"Thread blocked indefinitely in an MVar operation" when pressing ctrl+c repeatedly
|Reported by:||nstoddard||Owned by:|
I have a function for handling ctrl+c that looks like this:
handleCtrlC :: a -> InputT IO a -> InputT IO a handleCtrlC a b = H.handle (ctrlC a) $ withInterrupt b where ctrlC def Interrupt = pure def
This code is used in another line of code that looks like this: "handleCtrlC (Just "Interrupted") $ getInputLine "> ". That code is called repeatedly from a REPL.
When I press ctrl+c repeatedly while this is running, or just hold down the key combination, it eventually freezes up and a few seconds later gives the error "Main: thread blocked indefinitely in an MVar operation".
I'm running Haskeline 0.7.1.2 (which isn't an option in the "version" field - you should probably fix that) on Windows 7.
